The detachable plug P is provided with diametrically-opposed notches M, which when the plug is inserted in place are adapted to register with the projections or lugs M, formed on the head H. By slightly rotating the plug its liange will pass under the overhanging ends of the projections or lugs and be secured in place. The central plug P3 may be made hot by any suitable means and used on insertion to produce the iirst ignition of the oil and air charges. The head H is provided with hollow spaces H' and H2 for the entrance of air and also for oil, which oil is vaporized by Pass ages HS are also provided, through which mixed air and oil are delivered to the tire -chamber,

while other passages q are made for -the de# livery of air alone, it being inferred'that the oil and air mixture shall be somewhat richer in oil than is necessary for complete combustion and that the deficiency in air shall be made up or even increased to a slight excess by the free air-passages. When air is admitted in this general manner in addition to that mixed with the fuel, there will be a certain portion which will be exactly the chemical mixture desired, and therefore highly inflammable. the total flame well back against the head, and insures combustion under the best conditions. The air which reaches the head H is heated by being passed through the space C between the tank-casing and the tube J3 by means of the oval flattened pipe A', Fig. 1, also shown as entering the head H in Fig. 3, while Fig. 4 shows this pipe entering the casing from the back. The figure also shows the outward passage with the steam delivery ipe and shows a heat-insulating slab Z placed at the back of the vaporizer V2, where the gases turn after passing the vaporizer, returning over the out-side of the pipes J3.
